GISXControl Technology Preview Version 0.0.1

This project is a technology preview of a simple gauge LabVIEW XControl limited in features and visual aspect.

The XControl is based on a C wrapper on our Graphical Instruments Solution (GIS).

GIS is a set of instruments currently in development (Buttons, LEDs, Gauges, Knobs, Sliders, LCDs, Switches, Tanks, Thermometers, ...) with the following main features:

- C++ library based on Qt framework

- Multiplatform (Mac, Linux, Windows)

- Skin system based on SVG and XML to customize the appearance of each instrument

- Property system to customize the behaviour of each instrument

- Double license: Open source and commercial




The purpose of this technology preview is to see if such a library of XControls could be usefull and to get feedbacks from LabVIEW users community.





1. Copy mingwm10.dll, QtCore4.dll, QtGui4.dll and QtSvg4.dll into your LabVIEW installation directory (e.g. C:\Program Files\National Instruments\LabVIEW 8.6)

2. Open the project

3. Run the demo.vi

Linux and Mac

Not yet available. If you are interested in a Linux or Mac version please contact us.


Known issues:


- Performance issue when the value change rate is too fast. This will introduce a desynchronization between the current value and the displayed value.

This is due to the XControl architecture that stacks data changed events. See http://forums.lavag.org/XControl-DataChanged-events-stacking-t13459.html for more details.




If you have questions or if you want to give some feedback you can send mail to gisxcontrol@technogerma.fr or post directly on GISXControl LAVA support forum thread.
